Craig Olson will visit Camden Public Library Tuesday, Aug. 4, at 7 p.m. to give a talk on Identifying First Editions: The Treasures You Might Find on your Bookshelf. Olson runs the antiquarian book dealership Artisan Books & Bindery on Islesboro.

What makes a book rare — is it age or scarcity? Rare book dealer Olson will answer these questions, as well as talk about the basics of identifying rare books, how to care for one’s books and tips and pointers for budding collectors. He will bring a number of show-and-tell items including a couple of fairly valuable items for attendees to look at and hold. As time allows, he also invites attendees to bring in one item of their own for him to take a look at and give them an idea of value.

Artisan Books & Bindery maintains an open shop on the small island three miles off the Maine coast. In addition to general stock, Olson specializes in books on American history, art, architecture, interior design, fine press, and signed first editions.

“Given the fact that we are on a small island only accessible by ferry, it is best to call ahead to verify the best time to visit,” he said.
